Which of the following statements about species, as defined by the biological species concept, is (are) correct? i. biological species are defined by reproductive isolation. ii. biological species are the model used for grouping extinct forms of life. iii. the biological species is the largest unit of population in which successful reproduction is possible.

The correct answer is 1) biological species are defined by reproductive isolation and 3) biological species are the largest unit of population in which successful reproduction is possible.

According to biological species concept, two organisms belong to same species if they are capable of interbreeding and producing viable fertile offsprings.

This means that group of these members belonging to the same species is reproductively isolated from other group of species. Thus, according to this concept, successful reproduction is possible.

Therefore, option 1) and 3) is the right answer.

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.  

i believe it is c: genes for body color and wing size are inherited separately from each parent.
